As far as these days developing simulation fluid flow in different geometries are one the main concern of thermo fluid researchers , This study are going to employ Lattice Boltzmann Method as a computational method to solve some different geometries. This approach tends to demonstrate different accuracy and stability in two Relaxation time for Lattice Boltzmann Method(LBM) in lid driven cavity .Velocity field for different Reynolds number and aspect ratio in channel fluid flow are systematically presented to interpret developed vortex in different time. In this geometries multi particles are simulated for different Reynolds number and it is found that the percentage of removal particles in different time after stability is decreased by growing aspect ratio . In final section Multi-relaxation-time based on Lattice Boltzmann method is applied for simulation of backward-facing step .The obtained results shows position and length of the vortex. The numerical results obtained in this paper are in good agreement with the published experimental and numerical results.
